If you're posting as well, or at least commenting on stuff and having discussions with people you know (even if you just know them online), I think that's fine. Like forums, or being in group chats with friends on Facebook, or sharing photos you take with a specific community.
It's when you're only consuming (like scrolling TikTok or Instagram), or when your comments are written for the algorithm rather than for actual discussion (like on Reddit, or even Hackernews to an extent), that social media is an issue.
There's of course a risk that when they stop the drugs that hunger will drive them to re-establish those habits, but now that they have new habits that fight that hunger they are in a much better position to resist it than they were when they'd initially established their eating patterns.
The teenage data labeler thing was a bit of an exaggeration. He did found scale.ai at nineteen which does data labeling amongst other things.
Unfortunately he doesn't reveal any particular intelligence, insight, or drive in the interview, nor does he in other videos I found. Possibly he hides it, or possibly his genius is beyond me. Or possibly he had good timing on starting a data labelling company and then leveraged his connections in SV (including being roommates with Sam Altman) to massively inflate Scale AI's valuation and snag a Meta acquisition.
"Old fashioned forums" absolutely suck for discoverability. You have to waste time digging through posts, most of which are unrelated or just filler. No upvote/downvote and usually a mediocre threading mechanism. While we are on this topic, Discord is the same. IRC like applications are not an easy way to get to the point for the same reasons.
Discord and Reddit have so much repetition and fragmentation because there's no real organization of content, and people with no expertise often weigh in and even get upvoted because the average user is not particularly knowledgeable and the experts aren't on 24/7 looking for new posts to contribute to. On forums topics are stickier and get bumped when there's activity so experts more often find relevant threads and it's easier to judge reputations on forums.
Granted, badly managed forums are bad. If question threads from new users are mixed in with everything else they can quickly dominate search results. You need to be able to filter, but IME most forums do have pretty decent filters.
20 years after Reddit started, the best that the forums can offer is perhaps discourse.org, which is barely any better than traditional forums – sleeker UI for sure, but it's still fundamentally the same unworkable linear format. It's like sticking to magnetic tapes in the age of SSDs.
Even Facebook, one of the dumbest discussion platforms, has nested comments. Terribly implemented of course, but how does the platform designed for the lowest-common-denominator kind of user have more advanced discussion features than forums made for discussion connoisseurs? It is utterly baffling.
Forums shine as spaces for focused communities, where people have reputations and care about the subject matter. Time-sorted discussions are great because that's what's happening - a discussion in the community. You don't want to read someone's quip first, you want to get the whole context. You don't want there to be upvotes that people try to earn - there's already your reputation in the community. If someone's a troll or gives bad advice or is wrong, they'll get called out, or banned, or simply ignored as everyone knows they aren't respected.
Forums just aren't meant for generic content and it's not because of the UI, it's because the entire concept is not compatible with masses of semi-anonymous users with no commonalities.
